Light is
electromagnetic radiation within a certain portion of the electromagnetic
spectrum. The word usually refers to visible light, which is visible to the
human eye and is responsible for the sense of sight. Visible light is usually
defined as having wavelengths in the range of 400–700 nanometres (nm), or 4.00
× 10−7 to 7.00 × 10−7 m, between the infrared (with longer wavelengths) and the
ultraviolet (with shorter wavelengths). This wavelength means a frequency range
of roughly 430–750 terahertz (THz). (+info email)
